engine heating problems
I have a '65 Roadster with 300 hp small block and auto transmission. When it's warm outside, like summer, the temp runs around 200 to 210 degrees. I can't make myself believe that this is design temp. I've got a 190 degree thermostat in it and the stock radiator has been out of the car, cleaned and boiled out. As far as I know the water pump is doing its thing and the fan clutch is new. Is this normal?? Is there some coolant that will help. I would like to keep the car stock so aluminum radiators would be a last resort. Help.. Thanks for the reply!

RE: engine heating problems
This should really be in the tech section for your model, but...
Are you sure it is really running 200-210 degrees, or is that what your dash guage is reading? If you are running a 190 degree thermostat, it wouldn't be unheard of for your coolant temp to be 10 degrees higher. Remember that your thermostat is rated to open at 190, not keep your engine at 190.
So step one, use an external guage to measure your coolant and/or oil temperature. If you want the engine to run cooler, try the next step down in thermostat. If your radiator and waterpump are good, then the thermostat is your best starting point.
